Call of Duty Black Ops 4 has today released a brand new update for PS4, Xbox One and PC. There's a load of new content, including the Operation Apocalypse Z: Survivors DLC released last week, first on PS4.

The DLC is now available on Xbox One and PC.

But that's not all. Treyarch has also been tinking with the DLC and fixing some of the bugs reported by fans since it first went out last week.

On top of this, there are plenty more updates and bug fixes to the game.

Read on and you can take a look at the full patch notes released today for the new update.

But first, a word direct from Treyarch themselves.

Operation Apocalypse Z: Survivors arrives today on Xbox One and PC with all-new Contraband rewards and new game content in all modes, including Infected: Final Stand in Multiplayer, Pandemic in Blackout, and the new “Duck and Cover” Gauntlet in Zombies. Our PC 1.21 update is also live today, delivering new weapon tuning and gameplay improvements across the board.

Today’s update delivers new zombie-friendly tuning changes to Pandemic, and restores the original slide velocity values for Ajax, Seraph, Outrider, and Reaper in Multiplayer. Check out the full patch notes below to see what’s new today.

We’ve had a ton of fun playing Pandemic both here at the studio and online with all of you, and we’ve made some new tuning changes based on community feedback and game data to help out the infected team’s chances of victory. These changes include:

Increased infected sprint speed.

Increased infected ladder climb speed.

Increased infected melee lunge range.

Increased infected player resistance to Barricades and fire damage.

Reduced final Collapse delay from 30 seconds to 10 seconds.

Reduced final Collapse time from 90 seconds to 75 seconds.

This will allow the infected team to get to their targets faster, hit them sooner, and live longer against well-fortified survivors. We’re also slightly speeding up the action in the last Collapse to get everyone to the final showdown a bit faster.

These updates should result in a more balanced ratio of victories between the two teams – jump in and let us know what you think!

Almost there, Black Ops 3 Zombies fans... our fix for the “Gorod Krovi” main quest outro cutscene is currently planned to deploy on consoles as early as Thursday, August 14th. Keep an eye on Twitter to be the first to know when the patch is live, and thanks for your patience while we get this one over the finish line.
